The coarse powder mill is a new type of coarse powder equipment, upgraded from the vertical shaft sand making machine. It features a six-layer rotor structure with hammers arranged according to the crushing ratio. The finished coarse powder can reach over 70% in the 20-140 mesh range. The particle size is rounded, and the fineness can be adjusted. The hammers are made of high-strength alloy and can be rotated in all directions. Wear parts have a long service life. The investment cost is half that of similar coarse powder equipment, and maintenance costs are 30% lower.
Suitable for producing coarse powders of medium- to high-hardness stones. This machine is widely used for crushing a variety of materials, including limestone, granite, basalt, diabase, iron ore, copper ore, marble, brown corundum, and quartz sand.
The hammer head is made of high chromium alloy and can be turned over on all four sides for continuous use.the service life of wearing parts is long, and the investment cost is half of the same coarse powder equipment
The machine has a built-in 6-layer rotor structure, and the number of hammers is arranged according to the crushing ratio. The proportion of finished coarse powder in 20-120 mesh can reach more than 70%.
The finished product is cubic, with high stacking density and low noise during equipment operation.
We have a variety of models, suitable for various types of production lines; we can also customize according to customer needs.
The material first falls vertically from the top of the machine into the high-speed rotating impeller. Then, under the action of high-speed centrifugal force, it collides with another part of the material that is diverted around the impeller in an umbrella-shaped manner. Then, in the strong vortex formed between the impeller and the casing, they collide and rub against each other again or multiple times, causing them to be crushed. Finally, it is discharged from the discharge port at the bottom and then screened to the required finished particle size.
